What does Baba's story about the bundle of money teach us about the obstacles to attaining knowledge of Brahman?

Chapter 17 recounts a powerful lesson from Baba about the relationship between wealth and spiritual realization. After having a man pull out a bundle of money, which Baba initially called 'Brahman,' He then instructed, 'Roll up your bundle of Brahman; unless greed is completely destroyed, you will not find Brahman.' This illustrates that greed has an 'eternal enmity with Brahman.' The text states that a person whose mind is obsessed with earning wealth, cattle, or providing for children cannot attain knowledge of Brahman. If even a single trace of greed remains in the heart, all spiritual practices are said to go 'into the dust.'
